Science is under siege from lobbyists for those with self-serving economic or political interests. This is detrimental to our society's survival.

  • JohnDroz John Droz, physicist at retired @jcramer83: TY for your comments. In the ice-core slides you mention, I cited an example of using selective data in what is presented to the public. An 'example' is 'selective data' by definition. Ice core data is always delayed (i.e. will not be 2012) as it takes years to have legit ice cores to sample. The slides came from Foresight Institute, which is clearly identified in the references at the end. I was not using this as any 'proof' one way or the other about AGW. It was an example of how selective data can be misleading. 4 months ago

  • jcramer83 jcramer83 Mr. Droz, Thank you for teaching the public many insightful lessons on the scientfic method. I agree with most of your lessons, but many of the examples could have been better. I would like to ask some questions and provide some suggestions for your lesson titled, 'Seeing the WHOLE Picture is Critical' (begins on Slide 101). You wrote, 'One of the four Scientfic Process elements is to be comprehensive. Using selective data violates that.' I agree. You then ask the question 'what do the ice core samples from Greenland tell us about how our climate today compares to the past?' Over the next several slides you show GISP2 derived tempurature data. I should note that I did not see a citation for your data in your reference section below. Your graphs appear identical to the graphs created by Anthony Watts. To create his graphs, Mr. Watts used the data from Richard Alley's isotope analysis of GISP2 in 2000. The youngest data point is 0.0951409 (thousand years before year 2000). That corresponds to the year 1905. What do you mean by 'our' in 'our climate?' I can only guess you meant global climate (not many people live in Greenland). The most recent data point from your graphs is 1905. Considering many nonscientific people are blaming climate change on the combustion of fossil fuels, do you believe 1905 is a good representative of 'our climate today?' GISP2 is a proxy for the local temperature record at one spot above the Arctic Circle (72.6 N 38.5 W). 'Our climate' is global. Oxygen isotope ratios are only suitable for local records, not global records. Most analyses combine numerous datasets from different ice cores and other temperature proxies to get the 'whole picture.' Greenland temperatures tend to be offset by Antartica temperatures. Even ice cores which are near each other are not consistent with each other. GRIP ice core data is not identical to GISP2; and their core locations were only 20 miles apart. Why did you choose data from a single ice core to represent 'our climate?' Do you believe the GISP2 provides the 'WHOLE picture' about 'how our climate today compares to the past?' Maybe your example could be made more accurate if you change the phrase 'our climate today' with 'Greenland temperatures to 1905.' Otherwise, you used 'selective data' in your example. 4 months ago

  • bucknekkid bucknekkid Very interesting, but the period goes INSIDE the quotation marks. One would assume that someone who claims to know everything about climate science, global warming and sea level rise surely would know that. 4 months ago
